Refining is a key process for a complete oil pressing line because there are still some impurities, such as phospholipids, FFA, pigment, odor, etc. in crude oil. LD'e can provide you professional technical support and fabricate high quality oil making machines as per your specific requirements. Meanwhile, LD'e can provide you turnkey oil refining solution.
Main Steps of Edible Oil Refining
1. Crude Oil Degumming: Gums in crude oil are removed by hydration with the help of phosphoric acid.
2. Neutralization: Free fatty acids are neutralized by using sodium hydroxide and convert them into soap. Additional impurities are also removed by adsorption on soap.
3. Bleaching: During bleaching, unwanted pigments are adsorbed physically and oil will become much clearer.
4. Deodorization: It is used to remove unacceptable odors by steam distillation, the odoriferous compound are stripped off with the help of live injected steam into heated oil under high vacuum pressure.
5. Dewaxing (necessary for cold areas)
Some kinds of oil like sunflower oil, maize germ or corn oil contains waxes inside, if these impurities are not removed, the oil will freeze easily under low temperature, thus effecting oil quality and appearance. so this process is necessary in extremely cold areas.
Features Of Oil Refining Plants
1. Wide application: various kinds of oils can be refined by LD'e oil refining machines such as peanut oil, sunflower oil, soybean oil, coconut oil, palm kernel oil, rapeseed oil, rice bran oil etc.
2. The capacity of edible oil refining can be customized. The complete oil refining plant can work independently or together with whole oil production line.
